NURSING BOTTLE.

Application filed September 11, 1923. Serial No. 662,030.

To all whom it may concern: I

' Be it known'that I, MICHAEL M. WoLrn,

a'citizen of the United States, residing in' the city and county of Philadelphia, State of Pennsylvania, have invented new and useful Nursing Bottles, of which the following is a specification.

My invention consists of a nursing bottle which is composed of a nursing bottle proper and an inclosing casing therefor of transparent material admitting of presenting to view the contents of the nursing bottle proper as to quantity and condition adapting also the nursing bottle proper to be heated and retain its heat for a suflicient period owing to the heating space between the inclosing casing and the nursing bottle proper, this being occasioned without the employment of a vacuum or the vacuum principle as in a thermos bottle as practiced in other article of the class. Provision is also made for integrally connecting the nursing bottle proper and the inclosing casing at the respective necks thereof, whereby there is thereat no joint that may leak at the mouth of the bottle and said necks are strongly united and so the nursing bottle proper may be firmly sustained in position in the inclosing cas- 111 The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the scope of the claim. a

Figure 1 represents a side elevation of a nursing bottle embodying my invention.

Figure 2 represents a central vertical section thereof.

Figure 3 represents a transverse section on line 3-3 Figure 1.

Figure 4 represents a transverse section on line 44 Flgure 1.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings.

1 designates my improvement in a nursing bottle, the same consisting of the glass or transparent nursing bottle proper 2 of conventional form, and the glass or transparent casing 3 which incloses the same with an existing space 4 between them for atmospheric air.

The outer wall of the neck portion of the bottle proper blends with the .inner wall of the neck portion of said casing, said walls being fused together forming a single integral solid neck 5 for the two members, thus uniting firmly said portions and causing the nursing bottle proper to be suspended from i said neck 5 and sosustained thereon that it will not be liable to be broken therefrom prior to and during use.

On the neck 5 is the lip 6 for the attachment of a nipple. The bottom of the casing is nomally open, thus admitting access to the space 4 and the portion of the side of the casing above said bottom is threaded for the engagement of the base cap 7 which is formed of metal or other suitable material and adapted to close said bottom and consequently said space 4.

On the sides of the nursing bottle proper are the graduations 8 for indicating the amount of milk in the said nursing bottle proper, said graduations being visible through the transparent side ofthe casing 3.

The operation is as follows The cap 7 is removed and milk or another mixture if employed is poured into the nursing bottle proper to the extent required.

The nursing bottle proper is then stoppered' in any suitable manner, and the device placed in a refrigerator or cooler whereby the milk is rapidly chilled. When feeding 1s required, the device is removed from the refrigerator and immersed in a vessel of hot water until the desired temperature of the milk is attained, the bottom of the casing resting on that of said vessel, the hot water thus having full access to the bottom and side of the nursing bottle proper and to the space 4. Then the device is removed from the hot water and the base cap applied to the casing, thus closing the bottom of the latter whereby the nursing bottle proper retains its heat assisted by the heated air in the space 4, and so that infant may be nursed by the milk at the proper temperature to its full extent.

The stopper is, of course, removed and the nipple applied preliminary to nursing. It is evident that the mother or nurse may sterilize the nursing bottle proper preparatory to supplying it with milk, refrigerate the latter, and then heat it and after the heating operation have the milk retain its proper temperature in which condtion the infant is nursed, with the milk in a virtually pro-' tected manner.

It will be seen also that the device has a cationo parts, and the result is effected simplicit of construction without compliwithout the employement of a vacuum in the casin afterthe manner of a thermos bottle, as eretofore practiced, it being apparent also that both the walls of the nursmg bottle and the air in the space 4 are heated by the hot water, and so the milk rctains its heat for a period sufiicient for nursing. Furthermore, the nursing bottle proper primarily receives the milk, is subjected to v refrigeration and then to heatingwithout the necessity of transfer-rm the milk to another bottlev toaccom lish t e result. 7

Having thus descri d my invention what desire to secure by Let-' receptacle and'an outer,i.transparent air c'on- -26 portion of their'extent an verging toward their up r end-tovary the cross-sectional, area 0 said space and terminate in a single li uidpourm "neck 1 portion the walls of which are soli ,said

outer receptacle extending belowfthe'bottom.

of the-inner receptacle and being exteriorly 'screw-threadedand a screw-threaded closure 7 secured toftheiopen bottom or w rcmovably said outer receptacle.
